Spinocyrtia sp., Aulocystis commensalis Norway Point formation David Thompson

Submitted on 2007-02-12 by David Thompson

Location (approximate): Alpena, Alpena, MI

Strat unit: Norway Point formation

Submitter notes: This old Brachiopod was encrusted with several types of creatures living on her & they died with her also. There were boring sponges,'Clionoides' on the growth lines of her valves & Aulocystis tabulate coral on her brachial valve. There are some small bryzoan also but these are not identifiable. This brachiopod is from the Norway Point member, also known as the 'boat launch.' Scott Vergiels assisted in this identification.

Heliophyllum halli, Phacops , Nucleocrinus elegans Widder formation David Thompson

Submitted on 2007-02-12 by David Thompson

Location (approximate): Arkona, Lambton, ON

Strat unit: Widder formation

Submitter notes: This is another view in more detail of the Nucleocrinus blastoid from the Widder beds of Hungry Hollow. This shows the Phacops head to better advantage and the Heliophyllum coral behind them. The actual size of the blastoid is 1 cm. long exactly.

Dolatocrinus asterias, Platyceras bucculentum Traverse formation David Thompson

Submitted on 2007-02-12 by David Thompson

Location (approximate): Alpena, Alpena, MI

Strat unit: Traverse formation

Submitter notes: This is an unusual species with a Platyceras attached. Not too many Dolatocrinus with the snail attached. More often scars are found. This was found in the Alpena Limestone near a bioherm in Alpena. A dime is used for scale.

Dolatocrinus asterias, Platyceras bucculentum Traverse formation David Thompson

Submitted on 2007-02-12 by David Thompson

Location (approximate): Alpena, Alpena, MI

Strat unit: Traverse formation

Submitter notes: This view is of the top view of the crinoid showing the position of the Platyceras in relation to the anal opening & arms. This is from the Alpena Limestone but is from a bioherm in the formation where more crinoids are found. a dime is for scale.

Location (approximate): Thedford, Lambton, ON

Strat unit: Hungry Hollow formation

Submitter notes: This pieces is over a foot across. It has been donated the UMMP and is available for research purposes. With care, the strom can be lifted off the matrix to examine the back side.

Cladopora sp. Hungry Hollow formation Joseph Koniecki

Submitted on 2007-02-04 by Joseph Koniecki

Location (approximate): Arkona, Lambton, ON

Strat unit: Hungry Hollow formation

Submitter notes: Preparation of this specimen was conducted by carefully removing pieces from the matrix and immediately gluing them back together. Once the entire specimen was removed a map was made of its original orientation. The specimen was then placed in a quaternary ammonium solution for cleaning. The solution caused the glue points to dissolve. Then the clean pieces were assembled using the map. The final orientation represents the specimen as it occurred in the matrix and not necessarily in its living position, which may or may not have been the same. The specimen is about 14 cm across at its widest point

Phacops (Eldredgeops) rana crassituberculata Silica formation David Thompson

Submitted on 2007-02-04 by David Thompson

Location (approximate): , Paulding, OH

Strat unit: Silica formation

Submitter notes: This third view of this Phacops continues to show the hypostome (mouth cover) and shows the 'pits' along the lip of this taxon. The exact purpose of these has been debated as locking points for the pygidium when the bug is enrolled or it may be something completely unrelated. Post your ideas!

Phacops (Eldredgeops) milleri Silica formation David Thompson

Submitted on 2007-02-03 by David Thompson

Location (approximate): Sylvania, Lucas, OH

Strat unit: Silica formation

Submitter notes: This dual speciman shows a large adult & smaller trilobite. They are in the same layer & it would be nice to think of 'Mom & Baby' but the association may not be close at all. Clearly they were killed very quickly as they have not really started to enroll as this species often is found. This was self collected in Sylvania but prepared by Scott Vergiels of our 'Friends' who has prepared most of the trilobites I have posted. Sorry I'm old fashioned & these are still 'Phacops' to me.

Location (approximate): Paulding, Paulding, OH

Strat unit: Silica formation

Submitter notes: This is both a large & pristine example of this Taxon collected from Paulding Co. in Ohio. The speciman when collected had only a top of a few axial rings showing out of the shale.

Phacops (Eldredgeops) rana crassituberculata Silica formation David Thompson

Submitted on 2007-02-03 by David Thompson

Location (approximate): Paulding, Paulding, OH

Strat unit: Silica formation

Submitter notes: This speciman is unusual due to the preservation & preparation from the underside which shows the Hypostome or mouth area. The thin shell is translucent in this view. Crassi's have 84 eye facets as opposed to 104 in the milleri species of this Devonian trilobite.
